DOOR HOLDER.

Application fi1ed July 2,

To (ZZZ whom. it may concern:

Be it known that I, Join: J. NinonnKonN, a citizen of the United States, and resident of Port Washington, in the county of Ozaukee and State of l i isconsin, have invented certain new and useful Improvements in Door Holders; and I do hereby declare that the following is a full, clear, and exact description thereof.

This invention relates to door holders.

Objects of this invention are to provide a door holder which may be adjusted to accommodate variations in the height of the door above the floor, to provide a door holder which is automatic in its operation and permits the door to be swung thereover, thereafter holding the door in open position, and to provide a door holder which may be very simply produced and readily applied.

Embodiments of the invention are shown in the accompanying drawing, in which Figure 1 is a side elevation of the door holder showing it in engagement with an open door.

Figure 2 is a plan view structure shown in Figure 1.

Figure 3 is a modified form of the door holder.

Figure 4 is a sectional view showing a detail of the construction.

The door holder comprises a lower spring member 1 which is generally upwardly curved and an upper spring member which is provided with a downwardly curved or upwardly bowed portion 2, and a portion 3 reversely curved and conforming approximately to the arc of a circle. The upper and lower portions are held together by means of a rivet 4. They are provided with apertures on each side of the rivet through which attaching screws 5 and 6 are adapted to be passed to thus secure the holder to the floor.

As shown in Figure 1, the door holder is adapted to contact with the inner side of the door 7 In using the device, the door is swung open, the bottom portion of the door freely riding over the resilient holder and pressing it downwardly until the door passes the holder, a which time the holder 1923.

ill spring up into the position shown in Figure 1. To release the door, it is merely necessary to step upon the holder, thus pressing it downwardly below the lower edge of the door and permitting the door to be closed. It frequently happens that the distance between the lower edge of the door and floor is a variable factor for the different styles of doors. To accommodate this variation, screws 5 and 6 are provided through the curved portion 3 of the upper member and through a similarly curved portion of the lower member. Thus when it is desired to elevate the forward end of the holder the screw 6 may be tightened and the and provides a more extended bearing surface or contact surface. I

It will thus be seen that a holder for a door has been provided which is automatic in its operation. which may be adjusted to accommodate doors spaced at different heights from the floor, which may be released by stepping thereon, and which is of extremely simple construction.

Although a few forms of the invention have been described in considerable detail, it is to be understood that the invention may be variously embodied and is, therefore, to be limited only as claimed.

I claim:

A door holder comprising two spring strips having aligned contacting forward ends adapted to engage the rear face of an open door, said members being oppositely bowed and converging toward their rear ends, the rear ends of the members being similarly curved to provide a curved bottom surface adapted to rock upon a floor, means securing the curved portions together, and screws arranged inspaced relation to each otl er and passing through said curved portions and adapted to adjustably attach the holder to the floor, the adjustment being secured by rocking the curved portion on the floor, whereby upon relative adjustment of said screws, the vertical position of the forward end of said holder may be adjusted.

In testimony that I claim the foregoing I have hereunto set my hand at Port Vashington, in the county of Ozaukee and State of Wisconsin.
